Mason stands on the 5th step of a vertical ladder. the ladder has 15 steps, and the height difference between consecutive steps is 0.5m. h(n) models the height above the ground of mason's feet (in m) after moving n steps (if mason went down the ladder, n is negative). which number type is more appropriate for the domain of h? what's the appropriate domain?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
